I am considering sending my gearbox to Shep next year if I cannot find a good used unit. Will see how that goes.

I don't believe ShepTrans sells individual components, they only offer complete rebuild service to avoid warranty issues. I also believe the $1500 base level rebuild is done with only their own in house parts, the PPG stuff is an optional upgrade. And yes they are pretty big in the R35 realm, the shop that pulled my engine uses Shep for their 2000hp R35 build.

My goal is 350kw without e85, that's why I thought the 570cc would get the job done. I rarely drive mine and a full tank would last 2-3 months, so I can't really run e85. I also thought running R35 injectors with R35 AFMs should be a friendly combo to Nistune. Getting closer at 315kw during my last pull. Bought a 76mm Plazmaman but yet to install it, still waiting for my tuner's dyno to be repaired...

Are you running any cams? I'm still running factory air box, so maybe that's my problem. Or maybe because I'm running R35 injectors at factory fuel pressure. I read somewhere that R35 base fuel pressure is 1 bar higher and that's why it can get that much power out of 570cc. Not sure if that's true.

I got this divided charge pipe made not too long ago, if you are unsure about buying a whole intake piping kit. http://www.gtrusablog.com/2018/04/split-twin-turbo-pipes-by-alex.html This is what it looks like installed in mine.

That's a lot of power for -9's, especially only at 20psi. What other mods do you have?

Yeah the difference from 3000 to 5000 rpm is astonishing. My tuner made his pulls on stock R32 turbos, so with any decent aftermarket turbos the improvement should be more pronounced. He has actually pushed hard on those stock turbos and intends to blow them up as he has a pair of 2530 waiting to go on, but they are surprisingly tough.

I extracted more info out of him, really hope he doesn't mind me posting this. RPM across the top and load on the left. Question for you folks about how camshaft degree translates into cam gear degree. His HKS exhaust camshaft has a centerline of 110, and he gained across all RPM range by retarding his exhaust cam gear by 2 degrees. My Tomei has a centerline of 115, to get the same effect how should I adjust my cam gear?

My tuner just did some before and after pulls with HKS Vcam and shared on his Facebook. I would like to share that here for those thinking about Vcam. His car is still running on stock R32 turbos with steel turbine wheels. The pulls were done on E60 ethanol mix. https://www.facebook.com/houston.zauto/posts/1368728369930762

Much appreciate the review! Coincidentally my Do-Luck standard G Sensor should arrive in mail today. I am very curious about all the different settings I can play with.

You are referring to BNR32 right? I am not sure there is a rear outer tie rod bushing, but there is a ball joint and that is the part number you have.

I have similar set up as yours and also getting about ~300rwkw on 17psi with 93 AKI (not sure what that is in RON), so I'm interested to see your new results. I'm confident Nistune won't be an issue for you, and my tuner had done plenty of +400kw Z32s on Nistune with stock Z32 AFMs so I'm sure your other hardware is up to the task as well.

Great! I didn't want to do it before only because I didn't like the look of welds on it. Now there is fabricator in the US making his pipes look fairly seamless as seen in that picture, I am in.

Gathering thoughts/opinions on divided charge pipe. Looks like a fairly low cost way to improve consistency and perhaps some power. http://www.gtrusablog.com/2013/01/divided-rb26-twin-turbo-pipe.html
